Abstract

ABSTRAKTelah dibuat sediaan film sambung silang kitosan-sitrat yang mengandung verapamil hidroklorida. Tujuan dari penelitianini adalah untuk mengkarakterisasi film kitosan-sitrat yang disambung silang pada pH 4, 5, 7, membandingkan karakteristikfilm kitosan sitrat dengan film kitosan tripolifosfat, dan untuk mengetahui pengaruh pH natrium sitrat terhadap karakteristikfilm sambung silang kitosan-sitrat. Film dibuat dengan memvariasikan pH larutan natrium sitrat 4% yaitu pH 4, 5, dan 7.Sambung silang sitrat dibuat dengan menggunakan metode perendaman dan film dibuat dengan menggunakan metodepenguapan pelarut. Film yang dihasilkan dikarakterisasi meliputi analisis dengan FT-IR, evaluasi organoleptis, ketebalan,keragaman bobot, keseragaman kandungan, kadar air, ketahanan pelipatan, sifat mekanik, derajat pengembangan, danpelepasan obat. Karakteristik film kitosan-sitrat yang dihasilkan dibandingkan dengan karakteristik film kitosantripolifosfat.Hasilnya menunjukkan bahwa pH natrium sitrat mempengaruhi karakteristik film sambung silang kitosansitrat.Peningkatan pH larutan sitrat menyebabkan peningkatan persen kekuatan tarik dan penurunkan persen elongasi. Nilaikekuatan tarik tertinggi dan elongasi terendah dihasilkan oleh film kitosan-tripolifosfat, sedangkan persentase kumulatifpelepasan obat verapamil HCl terendah dihasilkan oleh film kitosan-sitrat pH 5.

Abstract

The development of a chemoentrepreneurship (CEP) oriented Colloidal Chemistry E-Module  assisted by 3D Page Flip Professional (3D PFP) is important to with produce students teaching material products that are related to their daily life environment and can stimulate students to create economically valuable and independent products. . To produce a very valid E-Module product, the user response is very good and it looks very attractive, research and development (R&D) is carried out with a 4-D model (Define, Design, Develop and Disseminate). The results of the validity of material and media experts on the developed E-Module are 95.54% and 95.5%, respectively, with a very valid category. The results of the limited test, namely a one-on-one test on 3 students, obtained information that the E-Module needed to be revised. While the user test results from 3 chemistry teachers obtained an average questionnaire score of 94% with very good criteria. Then the results of a limited test of 30 students obtained an average score of 88% with very interesting criteria. The resulting CEP-oriented E-Module products assisted by 3D PFP are expected to increase students' entrepreneurial interest.PENGEMBANGAN E-MODUL KIMIA KOLOID BERORIENTASI CHEMOENTREPRENURSHIP (CEP) BERBANTUAN 3D PAGE FLIP PROFESSIONAL AbstrakPengembangan E-Modul Kimia Koloid berorientasi chemoentrepreneurship (CEP) berbantuan 3D Page Flip Professional (3D PFP) penting dilakukan untuk menghasilkan peserta didik produk bahan ajar yang berhubungan dengan lingkungan kehidupan sehari-hari dan dapat menstimulus peserta didik untuk membuat produk bernilai secara ekonomis dan mandiri.  Untuk menghasilkan produk E-Modul yang sangat valid, respon pengguna sangat baik dan tampilannya sangat menarik dilakukan penelitian dan pengembangan (R&D) dengan model   4-D (Define, Design, Develop dan Disseminate). Hasil validitas ahli materi dan media terhadap E-Modul yang dikembangkan berturut-turut adalah 95,54% dan 95,5% dengan kategori sangat valid.
